Agentless

OpenCode is an open-source coding agent for the terminal. Its built-in build agent handles development work, the plan agent is read-only for analysis and exploration, and a general subagent supports complex searches and multistep tasks. The project also offers a beta desktop app for macOS, Windows, and Linux, so users can choose a CLI or desktop workflow.

Codex CLI provides a local command-line entry point to OpenAI's coding agent. After installing the binary or package, run `codex` to begin working from a project terminal on macOS, Linux, or Windows. The repository focuses on the CLI while directing users to separate IDE, desktop, and web experiences when those interfaces are preferable.

Cline works as a VS Code extension, terminal assistant, or SDK, allowing an agent to create files, run shell commands, browse the web, and call tools with human approval. Project rules and skills carry across its clients, while the SDK can register custom tools, lifecycle hooks, plugins, or MCP servers. It therefore spans personal coding assistance as well as custom agents and scheduled or embedded automation.

Open Interpreter is a Rust terminal coding agent designed for lower-cost and open models such as DeepSeek, Kimi, Qwen, and GLM. Its TUI can switch models and agent harnesses, execute commands inside native sandboxes, and use a built-in QA skill to operate and test web or native applications. Configuration and session state remain on the local machine.
